> I created an archiv with 7zip 9.20 containing the compress-1.7-src directory. Also tried it with 1.6 version and directory. I 
> downloaded the zip file and reziped it as 7z. The standard setting where used:
> Compression level: normal
> Compression method: lzma2
> Dictionary size: 16 MB
> Word size: 32
> Solid Block size: 2 GB
> I get an exception if I try to open the file with the simple line of code:
> SevenZFile input = new SevenZFile(new File(arcName));
> Maybe it is a bug in the tukaani library, but I do not know how to report it to them.
> The exception thrown:
> org.tukaani.xz.UnsupportedOptionsException: LZMA dictionary is too big for this implementation
> 	at org.tukaani.xz.LZMAInputStream.initialize(Unknown Source)
> 	at org.tukaani.xz.LZMAInputStream.<init>(Unknown Source)
> 	at org.apache.commons.compress.archivers.sevenz.Coders$LZMADecoder.decode(Coders.java:117)
